Quick Checks Before an AC Repair Visit
A few safe checks can sometimes get your AC running again. If they don't, they help your technician find the problem faster.
Check the thermostat
Make sure it is set to Cool, the set temperature is below the room temperature, and the display is on. A blank display often means dead batteries.
Check the breaker and outdoor switch
Central AC runs on a breaker in the main panel and usually a disconnect switch next to the outdoor unit. Reset a tripped breaker once. If it trips again, leave it off and call.
Check the air filter
A clogged filter restricts airflow and can freeze the indoor coil. Replace a dirty filter. If you see ice on the refrigerant lines, set the system to Off and the fan to On so it thaws before service.
